It is narrated from Sayyida Aisha (may Allah be pleased with her) that Shurayh (may Allah have mercy on him) asked her about the prayer of the Messenger of Allah (peace and blessings be upon him): She replied: The Messenger of Allah (peace and blessings be upon him) used to pray Tahajjud as much as Allah willed for him to pray, then when the time for Fajr prayer came, before leading it, he would pray two rak‘ahs, then he would go and lead the Fajr prayer. Shurayh (may Allah have mercy on him) asked her: When the Messenger of Allah (peace and blessings be upon him) would return to you from the mosque, what would he do? She replied: "He would begin with the miswak (tooth-stick)."
